ARP's Carburetor Float Bowl Kits are the smarter way to attach a Holley float bowl. These float bowl kits are made from 304 stainless steel and are virtually impervious to corrosion. A polished finish makes them an enhancement to any carburetor. They are 5/16" wrenching and are nominally rated at 180,000 psi. Available for both single and dual metering block Holley and Carter AFB applications.
